RAILWAY-TRACK.

SPECIFICATION forming part of Letters Patent No. 498,336, dated May 30,1893.

Application filed July 17, 1891.

To aZZ whom it may concern.-

Be it known that I, JOHN WALLACE, of the clty and county of Albany, inthe State of New York, have invented new and useful Improvements inRailway-Tracks, of which the following is a specification.

My invention relates to the construction of railway tracks, but moreespecially to tracks adapted to street-railways; and the object of myinvention is to provide a simple, cheap, and reliable construction ofrailway tracks in which the track-rails are secured in such manner thatthey are readily removable therefrom and can be easily replaced thereon.This object I attain by the means illustrated in the accompanyingdrawings, which are herein referred to and form part of thisspecification, and in which- Figure 1 is a transverse section of thetrack rail, chair, and fastener, showing the parts in position when thetrack-rail is secured to the chair, the turn-bolt for the fastenerbeing-in elevation. Fig. 2 is a similar section of the same parts,showing the fastener turned into a position corresponding to thelongitudinal slot in the top of the chair, as when the trackrail is notsecured to said chair. Fig. 3 is a perspective view of one end ofatrack-rail detached from a chair; and Fig. 4 is a perspective view ofone end of the chair detached from the track-rail.

As represented in the drawings, A designates my track-rail, whichembodies a head, 1, on which the car-wheels run, a lateral flange, 2,extending from said head horizontally, and a pendent longitudinal rib,3, formed, on the lower face of said flange. Preferably said rib is madeto extend over the entire length of each piece of track-rail. Atsuitable intervals the track-rail is provided with bolt-holes forreceiving turn-bolts, B, for operating the fasteners, C, for securingthe track-rails to the chairs the turn-bolts B and fastenings Gformingpermanent attachments to the track-rail A, so as to be removable withsaid track-rail when the latter is taken from the chairs, and saidbolt-holes should extend from the upper face of the flange 2 downwardthrough the lower face of the rib 3, and their upper extremity should becountersunk to contain the head of the turn-bolt. The head of each turn-$erial No. 399,820- (No model.)

bolt is provided with a slot, 4, or other depression, for receiving awrench or other implement by which said bolt can be partially rotatedwhen occasion requires,and a fastener, O, is secured to the lower partof each turnbolt in such manner that a rotative movement of the boltwill certainly produce a corresponding motion of the fastener O. Thelatter is preferably made in the form of aturn-button whose oppositeextremities will-when said fastener is turned in a transverse directionto the rib 3, as shown in Fig. 1-project beyond the opposite sides ofsaid rib.

E designates a metallic chair on which my track-rail A is secured, andsaid chair is made in the form of an oblong box whose bottom ispreferably left open. The top of said chair is provided with alongitudinal slot, 5, which extends toeach end of the chair and isfitted to receive the rib 2 of the track-rail A. Said slot is formedbetween the opposite edges of two inwardly-turned flanges, 6, which areintegral with the chair E, and the thickness of said flanges shouldslightly exceed the depth of the rib 2 of the rail A, so that, when thefastener G is turned transversely in respect to the rib 2, said railwill be drawn down into close contact with the top of the chair E.

In constructing railway tracks with my track-rails and chairs, the'latterwhich are preferably made four or five feet in length are spacedin such manner that the conjoining ends of two lengths of the track-railwill bear upon the same chair, but any required number of said chairsmay be placed intermediately between two chairs on which the oppositeends of the length of track-rails have their bearing. The chairs E areplaced so that the slot 5 of each chair will range in a true line withthe slots of the other chairs, and, after the tops of said chairs arebrought to a proper level, the track-rails A are fixed in position sothat the ribs 2 will freely enter the slot 5 in the chairs E with theconjoining ends of the track-rails in close proximity. In effecting theinsertion of the ribs of the trackrails into the slots in the chairs E,the fasteners 0 must be turned to range in line with the rib 2, but,when the track-rails are properly adjusted endwise, the turn-bolts Bshould have a quarter-revolution imparted to them,

and thereby the fasteners C will be moved in a transverse direction inrespect to the slot 2 so as to securely fasten the track-rails A closelyto the upper face of the chairs E. By turning the turn-bolts B, so thatthe fasteners C will range in line with the slot 2, the trackrails A canbe released so as to be readily removable from their places.

WVhat I claim as my invention, and desire to secure by Letters Patent,is-

1. In a railway-track, the combination of a chair provided with alongitudinal slot in its upper face, a track-rail having on its underside a longitudinal rib that is adapted to be easily entered into theslot of said chair, and a turn-bolt which passes vertically through saidrail and its rib and provided with a head fitted to receive an implementfor turning said bolt; the lower end of said turn-bolt having a fastenersecured thereto which is fitted to be turned transversely to the line ofthe slot in said chair so as to secure said rail to the chair; saidturn-bolt and fastener fOl'lIl ing a permanent attachment to said railso as to be removed with the latter from the chair, as and for thepurpose heroin specified.

2. A device for securing track-rails to chairs, consisting of aturn-bolt, B, having a head provided with means for receiving a wrenchor other implement for turning said bolt from the upper side of thetrack-rail; said bolt having secured to its lower extremity a fastening,0, consisting of abar Whichwl1en turned transversely to the line of aslot in the upper face of the chair E-will secure said trackrail to thechair, substantially as herein specified.

JOHN WALLACE.
